STAND FOR vPOWER-DRIVEN SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 226,802, dated April20, 1880.

` V Application filed September '24, 1879.

To vall whom it may concern:

'Be it known that I, LEOPOLD STERNBERGER, of the city and county ofPhiladelphia, in the State of Pennsylvania, have invented certain newand useful Improvements in Stands for Power-Driven*Sewing-Machines, ofwhich improvements the following is a specification.

The object of my invention is to firmly and steadily support a series ofsewing-machines operated by power from a common driving or countershaft, as well as to provide convenient facilities for the retention anddisposition of the garments or other articles manufactured upon saidmachines; to which ends my improvements consist in the combination oftwo or more sewing-machine stands arranged in line or in parallel lines,connecting bolts or braces uniting the adjacent legs of each pair ofstands, and removable work-receivers supported upon the connecting-boltsbetween the stands and above the drivingshaft, all as hereinafter fullyset forth.

In the accompanying drawings, Figure l is a vertical transverse sectiontaken between two of a series of sewing-machine stands arranged insingle line and with my improvements applied 5 Fig. 2, a verticallongitudinal section, and Fig. 3 a vertical transverse section, with thestands arranged in double line. Figs. 4 and 5 are sections on anenlarged scale, showing portions of the connecting-bolts and rollers forthe work-receivers as adapted to the double-line arrangement; and Figs.6 and 7 similar section as adapted for the single line, theconnecting-bolt in Figs. 4 and 6 being shown as a solid rod, and inFigs.5 and 7 as a tube; Figs. 8 and 9, similar sections, showing a clampfor uniting the connecting-bolt to an irregularly-formed leg; and Figs.10 and 11 are diagramsshowing the relative positions of the parts in thesingle and double line arrangments, respectively.

The stands which support the tables A of the series of sewing-machinesare arranged, either in single or double line, parallel and adjacent toa common driving or counter shaft, A', which is mounted in bearingsabove the floor of the work-room and serves to communicate power foroperating the machines. The stands are of the ordinary form-that is,

composed of two vertical legs or frames, a, united by a brace, a', andare placed at such a distance apart longitudinally as to afford spacefor the insertion between them of workreceivers of sufficient capacityto contain a desired quantity of the garments operated on.

Each of thelegs a of every stand is, when the machines are arranged indouble line, united to the adjacent leg ofthe next stand byahorizontalconnecting bolt or brace, B, placed about midway in its height, and inthe singleline arrangement two connecting-bolts are employed, locatedone at each side of the leg.

A rectangular open-topped case or work-receiver, O, divided into eithertwo or four com? partments, according as the machines are placed insingle or in double line, is supported upon each pair ofconnecting-bolts between two adjacent stands, the top of thework-receiver being slightly below the level of the tables A.

The work-receivers rest upon without being secured to theconnecting-bolts, so as to be removable at pleasure therefrom, andprovide separate receptacles for the work of the operators upon themachines adjacent to them, said receptacles enabling the work to be keptclean by preventing it from coming in contact witlrthe tloor, andlikewise facilitating'tl'ie cleansing of the work-room by aifordingnnobstructed access to the licor around the machines.

To prevent accidental displacement of the work-receivers, lugs or stopsc, fitting against the connecting-bolts, are secured upon their lowersides; and to facilitate the removal of the work-receivers I place uponeach of the connecting-bolts a roller, b, formed of one or more sectionsof tube.

The connecting-bolts B may be either solid or tubular, as preferred,being secured to the legs in the lirst case by shouldered and threadedend and nuts b', as in Figs-I, 6. and 9, and in the second by screws b2tapped into an internal thread, as in Figs. 5 and 7; and where the legis of irregular section the bolt is secured thereto by a clamp, b3, andwasherplate b4, as in Figs. 8 and 9.

In the application of my improvements I provide a light but firmbracing, imparting to IOO each stand the steadiness which is requisiteto resist the jarring and vibrations incident to the simultaneousoperation of a large number of machines. and also enable the work to behandled, stowed, and removed with facility, and the work-room andshafting to be kept clean and free from accumulations of dust, cuttings,or other rubbish.

I claim as my invention and desire to secure by Letters Patentl. Thecombination of a series of sewingmachine stands, arrangedloi'igitudinally in single or double line, a series of horizontalconnecting bolts or braces uniting` the adjacent legs of each pair ofstands, and removable work-receivers, each mounted upon a pair 'of theconnecting-bolts between the machine-
